7 Claims.

My invention is an improvement in sofas or settees of that special typewhich is convertible to a bed by extending a slidable section beyond oneend thereof to increase the length of the sofa, the width of theextended article of furniture corresponding with that of a single bed.

In the present instance my invention contemplates the provision of asmall sofaorsettee,commonly known as a love-seat, in which a slidablesection forming a part of the bed frame is normally housed within themain supporting frame and forms a part of the seat bottom thereof, tosupport a sectional pad or folded mattress providing the upholsteredpart of the seat when the article of furniture is being used as a sofaand to also provide the mattress when the structure is extended to bedform.

A further object of my invention is to provide a convertible sofa andbed in which the slidable section: forming a part of the bed frame, isconnected to the seat structure in such a manner that said slidablesection can be extended its full length beyond one end of the seatframe, whereby a comparatively short sofa or love-seat is providedconvertible to a bed of a standard length.

My invention further contemplates an economical arrangement for aconvertible sofa and bed which includes a dual seat-bottom frame or afolding bed bottom frame constructed of angle irons, with the two partsthereof hinged together and employed in connecion with the seatsupporting frame and associated slidable bed frame section, the dualseat and bed bottom frame when a folded forming a reinforced seat bottomfor the article of furniture in its use as a sofa or loveseat and a bedbottom when the structure is converted to bed form.

With these principal objects in view my invention consists in theconstruction of the dual element forming the seat and bed bottoms, andin the combination therewith of a slidable bed frame the feet 15 at theother end of the sofa.

Fig. 5 is an enlarged detail sectional view show-e .5 ing the means forconnecting the movable parts, including the slidable section of the bedframe and swinging section of the bed bottom.

Fig. 6 is a sectional view on the line 6-6 of Fig. 5. i

Fig. '7 is a perspective view of a corner of the main frame, theslidable and swinging sections being removed, and

Fig. 8 is a detail perspective view of the slid connecting the slidablesection of the bed frame: 1 to the stationary part of the seat and bedbottom.

In carrying out my invention I employ any conventional construction ortype of main frame which will present a sofa or love seat ofattractiveappearance, it being essential however that one end thereof bedetachable and movable with the extension section to form one of the endpieces of the bed as well as an end piece of the sofa. As illustrated inthe drawings the main frame is; in the form of a box-like seat framewithfront and rear sides II], II, permanently connectedat one end by acrosspiece I2 with corner posts l3, l3, and at the other end by a narrowbottom board I 4, the corner posts being extended to'form feet l5 at oneend of the frame while the other end is supported by feet l6, IS. Thestructure is completed as a sofa. frame by a movable end piececomprising corner'posts I1, I! connected by a crosspiece l8, and thismovable end piece 4 is a part of the extensible bed frame section,hereinafter described, with the lower ends of the corner posts shaped toform feet I9 cooperating with the feet l6 of the main frame so as tomatch Within the main frame there is secured a rectangular frame 28,forming one part of the combined seat and bed bottom, said frame being,preferably constructed of angle bars with side rails 20a, 20a and across rail 20b at one end, while the other ends of said side rails areconnected by hinges 2|, 2| to the contiguous ends of a similar seat andbed bottom frame 22, consisting of opposite side rails 22a, 22a andcross rail 22!). The frame 20 upon which the frame 22 is folded ispermanently attached at one end to the crosspiece [2 of the main frameby screws 23 (Fig. 6) and at its other end is supported on and attachedto angle brackets 24, 24 mounted on the crosspiece I4, it being noted byreference to Fig. 7 that the ends bf the side rails or angle bars ofthis frame are securely attached to the 7 angle brackets by rivets 25,25, so that the depending member of each side bar or rail will bespacedfrom the angle bracket and a short distance from the adjoiningside of the sofa frame for the operation of the slidable element(hereinafter described), connecting the extensible ,sec-

. '7 tion of the bed frame to the stationary "section.

This arrangement provides the supporting means for'a dual seatand'bed'b'ottom frame'adapted to be unfolded for the'purpose of formingthe bed bottom, and as it isintended to use any conventionalconstruction'or type ofwire-fabric 'gfor the seat and bed bottom, withthe usual helical springs (not shown), there is considerable tension onthe bed frame laterally and consequently i bed frame by'riVetsZSw'. V

I provide a tubular brace 26 extending between to brackets '28, 28fastened to the corner posts 11,1! of the movable end piece'of'the; sofaand at their inner ends by slides 29, to the angle bars ZUa, 20a; of thestationary section of the dual seat and bed bottom, the aforementionedslides and side rails of the extensible section of a V the bed framebeing disposed at the outer sides 35: V V

of ,the dual seat andbed bottom frames 'to travel in-the spacebetweentheside rails of thesta tionary section or said frames and side pieces of hfa-,,@ I

gThe slides'are of a particular construction to travel oonthe'a'n'glebars 20a, ifor which purpose each slide is provided withastraight'flange 29a at its upper edge, overlying the upper'member ofsaid angle bar, andwith'an outwardly and upwardly turned flange 29b'atits lower edge to receivethe dependingmember of said angle bar therebyinsuring positive sliding engagement.

7 The side rails 21 of the extensible section of the bed frameareconnected to the outer'ends of Y 7 these. slides by pins 30, and inorder to provide ',for the desired extraordinary extension of thissection the pin" connecting each slide engages a hole 290 in the slideand a horizontal slot 3| in ,the side rail 21; that is to say, by thisarrangement the side rails of the bed frame section may be ofsubstantially the same length as the side pieces of the seat'frame, andin the closing oper-- ation of this bed frame section the inner ends ofthe side rails thereof move on the slides or con- -necting pins 38 thefull length of theslots so as to. extend approximately to the crosspiecel2 of the mainframe (see dotted lines, Fig. 4); Conversely when this bedframe sectionis extended to its fullest extent it is entirely beyond theend of the seat frame .(see Fig.4) with its inner end firmly supportedby the projecting ends of the slides, thus providing a bed frame of astandard length and a comparatively short sofa or loveseat. When theslidable bed framesection is ex- 7 b tended it receives the foldingsection of the hinged bed bottom, and for supporting the outer or free:end'of this folding section on the bed frame within the slidablesection thereof it is provided with projecting pins 32 seating incorresponding recesses '33 in the side rails 21.

The particular construction of the extensible bed frame section and itsslidable connection with the stationary seat bottom frame, including thefolding part of the bed bottom, provides metal parts for a convertiblesofa and bed of simple'and economical construction, durable in use, and

which may be easily manipulated in converting the sofa or love-seat tobed form, and vice Versa.

As will be seen the parts are locked in extended position or bed form bythe engagement of the pins 32 in the recesses 33, and in order to lockthe extensible bed frameisection in place when the article of furnitureis being used. as'a sofa or love-seat-any suitable form of catch devicemay be employed, one member, as 34, of which is secured to the posts llof the movable end piece and the other member, 35, attached to theunderside of the bottom board M of the seat As no claim is made to thiscatch or locking device, per se, it is not shown tintdetail, it beingunderstoodhjowever that one ofthe memframe.

bers, .34 or 35, may be in the form of spring jaws engaging the othermember, or one of the conventional forms of friction catches for holdingthe slidable section closed and force to open and close it.

v 7 From the foregoing de scription in connection with the drawings "itwill be readily seen that the construction provides acomparativelyshortsofa. l inthe form of a love-seat, as illustrated in Fig.

l, adapted for day use, andthat byextending the bed/frame section itwill serve to support the folding-section of the bed bottom so that thepad orupholstered' portion ofthe seat, which is removedxin the operationof converting the article of furniture from a seat to a bed, is unfoldedtrated in 'Fig. 2. When the article of furniture requiring a little jan'd serves as the mattress for; the bed, illusis 'used as a sofa orlove-seat it is placed near 'a'wall, and as the seat is a little widerthan usual for a sofa, pillows may be used to form a back 7 for the sofaor love-seat.
